Objective To evaluate the anti-tumour effect of 60℃ LipiodoI in the embolization of VX_2 hepatocarcinoma in rabbits.Methods VX_2 carcinoma cells were surgically implanted into the left liver lobe in 30 male New Zealand white rabbits,which were randomly divided into 3 groups by figure and table method with 10 rabbits in each group.Physiological saline,Lipiodol(37℃),and Lipiodol(60℃)were injected in each group via hepatic artery and liver cancer was embolized.The volume of tumour and serum level of aspartate aminotransferase(AST)were observed after one week,and the survival period of VX_2 rabbits was also observed.Results In the group of Lipiodol(60℃),the growth rate of tumour(0.92? 0.21)was significantly lower than that of control group(3.48?1.17)and Lipiodol(37℃)groups (1.69?0.26),respectively(F=34.95,P0.05),but was significantly higher than the control group(68.6?6.6)U/L(t=19.24,P

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

Objective To investigate expressions of surface maturation markers, secreting cytokines and the stimulat?ing effect on T lymphocytes in the dendritic cells (DC) from peripheral blood of tuberculosis (TB) patients after loading dose treatment. Methods TB patients who received initial treatment (n=68) were collected at the fifth hospital of Shijiazhuang from 2013 June to 2014 January. Base on clinical diagnosis and treatment guidelines of tuberculosis, they were divided into sputum smear-negative group (35 cases) and sputum smear-positive group(33 cases). Forty cases of healthy adult were se?lected as control group. Mononuclear cells were isolated from peripheral blood and were cultured in medium to differentiate into DCs. Expression levels of CD83 and CD86 on DCs were examined by flow cytometry. The proliferation of allogeneic mixed lymphocyte stimulated by DCs was dectected using MTT assay. Contents of IL-12, IL-10 and INF-γin the cultural supernatant of DCs and blood serum from TB patients were detected by ELISA. Results Compared with controls ,the ex?pressions of CD83 and CD86 on DCs in TB patients after loading dose treatment decreased obviously(P<0.05), and the ability to stimulate the proliferation of lymphocytes reduced evidently(P<0.05). What’s more, IL-12 level increased mark?edly(P<0.05)while IL-10 and INF-γlevels presented no significant difference among the three groups (P>0.05). Conclu?sion The expressions of maturation markers of DC cells of the peripheral blood in TB patients after initial treatment de?creased. The ability of stimulating mixed lymphocyte proliferation is also significantly reduced while secretion of IL-12 was enhanced.

AIM: To investigate the mechanism of the AP-1 signal transduction pathway inhibited by JIP in nasopharyngeal carcinoma cells. METHODS: AP-1 activity was triggered by Dox-induced LMP1 expression in Tet-on-LMP1-HNE 2 cells (L7). The retention of phospho-JNK in the cytoplasm caused by JIP was examined with immunofluroscence assay. RESULTS: 24 h after transfection of L7 cells with the JIP expression plasmid, the translocation of activated JNK was inhibited, which resulted in the retention of phospho-JNK in the cytoplasm and down-regulation of the AP-1 activity. CONCLUSION: JIP down-regulates the activity of AP-1 through the inhibition of the translocation of JNK.

Background Experimental data have shown tnat polymorpnisms in tne angiotensm-converting en- zyme 2(ACE2)gene are related to echocardiographically determined parameters of left ventricular mass,structure or function in the general population whether ACE2 genotype influences the effect of angi0tensin Ⅱ receptor blocker which improve left ventricular remodeling and function is unknown.Objective To investigate the association be- tween ACE2 gene G9570A polymorphism and the effect of irbesartan on left ventricular structure and function in hy- pertensive patients.Methods Two hundred and five male patients and 190 female patients who were preliminaryly diagnosised with mild and moderate essential hypertension were treated with irbesartan for 48 weeks with initial dose of 150 mg/d and titrated to 300 mg/d to reach the targed BP.Gene polymorphisms of ACE2 G9570A were detected by PCR-RFLP methods.The association between changes in the SBP,DBP,parameters of left ventricular struc- ture and function and genotypes of the ACE2 gene locus were analyzed.Results Irbesartan reducted in blood pres- sure in all patients(P

DNA microarrays have been acknowledged to represent a promising approach for the detection of viral pathogens. However, the probes designed for current arrays could cover only part of the given viral variants, that could result in false-negative or ambiguous data. If all the variants are to be covered, the requirement for more probes would render much higher spot density and thus higher cost of the arrays. Here we have developed a new strategy for oligonucleotide probe design. Using type I human immunodeficiency virus (HIV-1) tat gene as an example, we designed the array probes and validated the optimized parameters in silico. Results show that the oligo number is significantly reduced comparing with the existing methods, while specificity and hybridization efficiency remain intact. The adoption of this method in reducing the oligo numbers could increase the detection capacity for DNA microarrays, and would significantly lower the manufacturing cost for making array chips.
